Abstract

L'invention un appui-tête (1) comprenant deux tiges (2) pourvues de crans (3) de verrouillage qui sont montées en coulissement dans un boitier (4), et un dispositif de verrouillage comprenant un fil (5) élastiquement déformable entre une configuration de verrouillage et une configuration de déverrouillage, ledit fil étant monté fixe dans ledit boitier et conformé de manière à adopter sa configuration de verrouillage en l'absence de contrainte, ledit appui-tête comprenant en outre une traverse (7) pourvue de deux surfaces de came (8) coopérant avec deux zones (9) dudit fil formant suiveurs de came, de sorte que ladite traverse actionnée vers une position de déverrouillage amène ledit fil en configuration de déverrouillage, ladite traverse coopérant avec un moyen ressort (10) l'actionnant vers sa position de verrouillage et avec un bouton (11) permettant de la déplacer vers sa position de déverrouillage à l'encontre dudit moyen ressort.The invention a headrest (1) comprising two rods (2) provided with locking notches (3) which are slidably mounted in a housing (4), and a locking device comprising a wire (5) elastically deformable between a locking configuration and an unlocking configuration, said wire being fixedly mounted in said housing and shaped so as to adopt its locking configuration in the absence of constraint, said headrest further comprising a cross member (7) provided with two cam surfaces (8) cooperating with two zones (9) of said thread forming cam followers, so that said cross member actuated towards an unlocking position brings said thread into the unlocking configuration, said cross member cooperating with a spring means (10). 'actuating towards its locking position and with a button (11) allowing it to be moved towards its unlocking position against said spring means.
